Primer over factory paint

Long term project. 1990 C1500 truck. Factory paint, no other paint work.

Paint is faded but intact. No surface rust showing through.

I want to shoot it in red primer (it's butt ugly two-tone gold now) and work on it along with my other two projects.

No bare metal, so can I go straight to high-build primer?

It will be daily driven and exposed to weather.

Sure thing..just give it a good scrubbing and sanding so you remove any loose paint..

absolutly,just give it a good sanding with 180 and get any loose or whitish clear off,if there is any..we do it all the time..But it doesnt have to be a build primer...I'd use an epoxy then guide coat it to find the dings...

After owning a 90 GM truck that the paint went south on I would be very hesitant to apply any paint on top of it. The paint on my 90 GM truck turned chalky and the clear coat was peeling right off when I sold it. That time period of GM vehicles were know for lousy paint jobs. At the very least I would apply an epoxy sealer coat first.

I would have to agree with this. Our family has owned more than a handful of these trucks and even up to my 96 the paint is flaking off slowly but surely. In a particularly sun-drenched place like here in AZ it's pretty common to see a C/K pickup that's showing as much grey primer as it is paint (especially on the white ones for some reason unknown to me) from the 88-01 era.

You don't need hi build primer unless you're doing bodywork. I would sand whole truck with 320, breaking into factory primer, then wet sand it with 400 and seal it. You should be able to put your paint right over sealer. Or you can take a risk and shoot paint right after you wetsand it with some 600 grit.

Ok...truck is now red!

I used TCP Global Kustom Shop DTM Epoxy Primer/Sealer along with the KR85 slow reducer.

Mixed it just as the tech sheet said and it looks pretty nice.

The truck will take a back seat now to my two other projects but first I have a question.

Can I sand the primer/sealer with a fine grit paper to smooth it out a bit more?

If it were smoother it will be easier to wash it and keep it clean.

What do you guys think??

Sure you can sand it.
I'd wet sand it with 320 or 400; you could even
start the blocking process on the flat panels.

Just be careful to not sand through the primer,
since that'll be the topcoat for awhile....

the only thing is it will mlose whatever sheen it has and be flat (in color) but guide coat it before sanding ....I think you'll find once you start sanding you wont be able to stop and when its done you''l want to paint it right away ....thats the way I an anyways....I'd HAVE to leave it just the way it is.....
So, how'd you like that global anyways??? I've been hearing a lot about it lately...
